Resonances with a relatively higher lifetime might not go through the rescattering and regeneration processes. Thus, in contrast to \(K^{*0}\) , \(\phi \)  meson can act as a tool to locate the QGP phase boundary. The transverse momentum (\(p_{\rm T}\) ) spectra of \(\phi \)  meson will not be distorted during the hadronic phase. Hence, by using the \(p_{\rm T}\)  spectra of \(\phi \)  meson, we can extract information about the location of the QGP phase boundary. To do this, we fit the \(\phi \)  meson \(p_{\rm T}\)  spectra with the Boltzmann-Gibbs blast-wave (BGBW) function up to \(p_{\rm T} \sim \)  3 GeV/c [1]}, [2]}. From this, we can get the freeze-out temperature (\(T_{\rm th}\) ) and the average velocity of the medium (\(\langle \beta \rangle \) ), which can then help us to estimate the effective temperature (\(T_{\rm eff}\) ) by the formula [3]};
\(T_{\rm {eff}} = T_{\rm {th}} + \frac{1}{2}m\langle \beta \rangle ^{2}.\)
